Title: | Hybridization of Discontinuous Galerkin FEM for Second Order Elliptic Problems |
Time: | 3:00-4:00 pm |
Place: | Blocker 628 |
In the last several years B. Cockburn and J. Gopalakrishnan
introduced a new hybridization technique for mixed FEM for second
order elliptic equations. The main ideas of this technique combined
with the the technique of lifting operators from the discontinuous
Galerkin approximations led to a unified hybridization technique
for discontinuous Galerkin (DG), mixed, nonconforming, and
conforming finite element approximations of second order elliptic
problems. In the talk we shall discuss this general hybridization
framework for second order elliptic problems, which is
characterized by
(1) the finite element spaces of the local solutions,
(2) the numerical traces of the solution and the flux, and
(3) the space of the Lagrange multiplier.
